As shown in Figures 1to 3 inclusive, this sheet is wound upon a roller 10 which has trunnions11 and 12 journaled in opposite side portions 18 and 14 of triangularshaped plates 15 which comprise a frame. The roller 1() is by preferencedisposed in one of the corner portions of the base of the frame and inalinement with a second roller 16 disposed in the apex portion of theframe and having trunnions 17 and 18 journaled in the side portions 13yand 14. The sheet 5 extends from rollerV 10 and is trained aroundV acylindrical brush 19 vcarried 'by a roller 20 whose ends are journaledin the side members 18 and 14 of the frame, the brush 19 being disposedin the corner portion of the base opposite to the roller 10. The sheetextends under the brush and therefrom is directed laterally and securedto the roller 16. Thebrush 19 is of a size to extend beyond the base ofthe frame so that the section of sheet 5 between roller 10 and brush 19is caused to project beyond the edge of the base. .In this way thepresence of the base of the frame does not prevent the section of thesheet between the roller 10 and" brush 19 from making contact with thewall or ceilino'.

handle 21 having a fork 22 at one end is formed integral with orotherwise connected at the end of the corner portions of the sidemembers 13 and 14 adjacent' to the roller 10. This handle 21 slopesoutwardly so as to provide a clearance for the hand of the operatorbetween the handle and the wall in the operation of the device. Thetrunnions 12 and 18 extend beyond the ad jacent side member 13 of theframe and have secured thereto pulley sheaves 23and 24 around which aretrained an endless belt 25 which transmits motion from the roller 10 tothe take-up roller 16.

In the operation of the device the sheet 5 as described is rolled uponthe roller 10, then extended underneath brush 19 and connected totake-up roller 16. The operator then proceeds by pressing the section ofthe sheet between roller 10 and brush 19 to the surface of the wall orceiling to which a coating of coloring matter has been applied andbefore the coating has dried. The application of the device is bypreference initially made to the upper portion of a wall, and the deviceis manipulated so that the entire section between the roller 1() andbrush 19 makes contact with the wall. The operator then'proceeds to movethe device vertically downward and in so doing the friction between thesheet and the wall, and due to the pressure applied to the frame by thehand of the operator, causes the sheet to unwind from roller 10,whereupon takeup roller 16 is operated through belt 26 to wind the sheetas the same is unwound from roller 10. Y

It will be noted by reference to Figure 2 that pulley 23 is smaller thanpulley 24 so that take-up roller 16 rotates at a higher rate of speedthan roller 10. This difference in speed between the rollers preventsslack in the run or section between the brush and roller 10, andoperates to ymaintain the sheet taut. It will, of course, Vbe understoodthat provision is made by having the belt relatively loose to preventthe roller 16 from exerting a pull on the sheet that would operate tobreak the same. The employment of the brush 19 is ideal in connectionwith sheets provided with indentations, such as shown at 8, or withnon-absorbent areas, as shown at 9, but in practice it has been foundundesirable *to use the brush when cut-out portions, such as 6, are usedfor patterns. Vhen using a sheet, such as shown in Figure 1, provisionis made to eliminate Contact between the brush and the sheet by anadjustable plate 26 connected at one end to a transverse roller 27 whichis adaptedto be turned by having its ends mounted in the sides 13 and 14of theframe. l The 'free end of the plate is rounded by curving the sameoutwardly, as at 28, and the plate is adapted to occupy a positionupwardly and away from the base and brush 19, or to be moved downwardlyand outwardly and toa position tangentially of the brush, in whichposition the rounded end portion 28 extends well beyond the base of theframe and the brush, as shown by dotted lines inFigure '3. The dottedline position of the plate 26 permits the sheet to be trainedV aroundthe curved portion 28 and the presence of the brush holds the plate inposition under the pressure which is applied to the framewhen the deviceis in use. In that the sheet of the present invention is relativelyinexpensive to provide, it is proposed that after each use to discardthe used Vsheet and replace with a fresh or new sheet. This prac tice,however, can be left to the discretion of the operator and will, ofcourse, be governed by the absorptive qualities of the sheet and thecharacter of coloring matter used.

Although I have shown and described one embodiment of my invention, itis to be understood that the same is susceptible of various changes; andI reserve the right to employ such as may come within the scope of theappended claim.

I claim: y

A decoratorsdevice comprisinga rolled sheet of absorptive material'adapted to be placed in contact with certain areas of an undriedcoating of liquid coloring material Vrolled thereover and absorb thesaid Ina-teral, said sheet being provided with a nonabsorptve patternadapted to isolate certain other areas of the coating from theabsorptive action of the sheet in the unrolling of the sheet upon thecoating, and means for supporting said roll including a rotary brush forcausing Contact between the sheet and the surface being operated uponand 1 means for re-rolling the sheet as the same is moved from the firstnamed roll.
